Bugs in space

Hardy Earth bacteria can grow in lunar soil - New Scientist Space

Planning on colonizing the moon? Cyanobacteria may be your best friend:

The cyanobacteria were taken from hot springs in Yellowstone National Park in Wyoming, US. When put in a container with water and simulated lunar soil, the cyanobacteria were found to produce acids that are amazingly good at breaking down tough minerals, including ilmenite.

They use the nutrients freed up this way to grow and reproduce. "This is unbelievable," Brown told New Scientist. Breaking down the same minerals artificially would require heating them to very high temperatures, which uses enormous amounts of energy, he says. Cyanobacteria, on the other hand, use only sunlight for energy, though they do their extraction work more slowly than heating the soil artificially.
